Abstract

This invention discloses a device of WCDMA chip-level process device including a bus interface module, a sample data interface module, a chip-level output interface module, a register module connectedto said bus interface module and used in maintaining the match information necessary for normal work of the device, a clock management module connected to the bus interface module and the sample datainterface module for controlling and managing the clock of the device, a framing process module for framing based on the path time sequence information in the match information and the generated counting value to get frame head signals and a descramble and integral module used in descrambling, de-expanding and integral process to get and output symbol stage IQ data.

Description

technical field [0001] The invention relates to the field of WCDMA (Wide Code Division Multiple Access, wideband code division multiple access) mobile communication, in particular to a chip-level processing device for WCDMA downlink reception. Background technique [0002] At present, there are three mainstream solutions in the field of third-generation mobile communication, including WCDMA technology, CDMA (Code Division Multiple Access, Code Division Multiple Access) technology and TD-SCDMA (Time Division-Synchronized Code Division Multiple Access, time-division synchronization Code Division Multiple Access) technology, these three technologies are based on the principle of spread spectrum communication, because WCDMA evolved from GSM (Global System for Mobile Communication, Global System for Mobile Communication), it has a wider use base, WCDMA can provide Voice, variable-rate data, and multimedia services can adapt to various environments and realize global roaming, larg...
